    Opis:
    The lack of knowledge about seasonal dynamics and impact of deer browsing on deciduous saplings in plantations in managed forests in Poland raises difficulties in assessing the impact of cervids on forests and in selecting effective methods for protecting plantations against damage caused by deer. The studies covered 1129 saplings of sycamore, oak, beech, linden and birch species that were planted on the unfenced sites accessible for animals and fenced sites left for comparison.

    Opis:
    The results of the inventory of damage caused by roe deer in a 2−year−old apple orchard in central Poland permitted to evaluate the browsing intensity as well as the relationship between biometric characteristics of trees and browsing intensity. The research showed that damage caused by the roe deer was mainly caused by shoot browsing, then rubbing the velvet antlers against trees and bark stripping. In one winter, roe deer damaged 35% of the orchard by browsing even up to 100% shoots on an individual tree. Significant differences were found between the intensity of browsing the different varieties of apple trees. The largest damage was noted in the case of the Ligol variety (35% of shoots on average), while the smallest – for the Idared and Golden Delicious varieties (approximately 5% of shoots on average). Branching and tree height were not found to affect the level of damage. When establishing forest hunting grounds, the Ligol variety, eagerly browsed by roe deer, should be planted on browsing plots, while Idared and Golden Delicious varieties – in orchards designed for fruiting.

    Opis:
    Effects of ungulate pressure on the development of young generation of trees is one of the most important issues in ecology and forestry. Ungulate pressure influence on the development of natural regeneration has been also reported from several national parks. Our study on the effects of ungulate browsing on the young generation of trees was conducted on more than 500 sample plots controlled during one growing season. The overall browsing pressure ranged from 7.6% in seedlings to 20.3% in low saplings. The pressure of ungulates on the regeneration of Picea abies, the dominant species in the Tatra National Park, was by and large below 1%. Broadleaved species were browsed more frequently. The relationship between the plot altitudes and browsing intensity was statistically significant for seedlings and low saplings; at the higher altitudes, the browsing pressure was greater. There was also observed a statistically significant relationship between the type of former management and the browsing degree in seedlings; in the areas subjected to “landscape protection”, the intensity of browsing was higher when compared to strictly protected areas. Pressure exerted by ungulates on tree regeneration was very unevenly distributed, i.e. some plots were heavily browsed and many others - not browsed at all. The most affected tree species were Salix caprea and Sorbus aucuparia, although the percentage of browsed individuals rarely exceeded 50%. Other species favored by ungulates was Acer pseudoplatanus; despite the high browsing pressure, this species was present among seedlings and tall saplings, suggesting that it would be able to recruit to the tree layer. Abies alba was browsed less frequently than the deciduous trees; however, among the tall saplings it was the third most browsed species.
